Police said the situation was tense but under control.
According to residents, Amethi gets just about 10 hours of power supply every day.
The Congress Tuesday said the BSP was not paying attention to the woes of Amethi residents as it was Rahul Gandhi's constituency. The party also criticised the police for using force to disperse the protesters.
'As Amethi constituency is represented by Rahul-ji, the state government is adopting a step-motherly attitude towards Amethi ... as a result, it is reeling under a power crisis,' said state Congress spokesperson Akhilesh Pratap Singh.
'The situation in Amethi would not have gone out of control, if the police and the district authorities had tried to pacify the protesters by holding talks. The way police baton-charged people in Amethi cannot be justified under any circumstances,' he added.
Demanding action against police and district authorities, the Congress party has sought the governor's intervention.
'Our foremost demand is that those arrested for carrying out protests against the poor power supply should be released immediately,' said Singh.
Meanwhile, the Amethi Vyapar Mandal observed a 'black day' Tuesday protesting the alleged police atrocities and shut their business establishments.
